Public bug reported: I wrote a udev rule that would not trigger when expected. I spent 2 days working on it, trying to understand what the problem was. I finally figured it out -- it was a matching problem:
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1890836 The most verbose output possible is with the log level set to "debug". This level of logging does not show users what criteria is being checked and what the result is. So users are working in the dark. We have to guess what udev is doing. And we're bad at it, because if we could guess correctly we probably would have written the rule correctly in the first place. Consider procmail. This is an application where users write rules that contain matching criteria. When Procmail doesn't work as expected, the logs show in detail what criteria matches and what does not. This is what udev needs. ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1890890 Title: more debugging verbosity for udev rules needed Status in systemd package in Ubuntu: New Bug description: I wrote a udev rule that would not trigger when expected.
